Researchers develop a 360-degree holographic display

Researchers at USC have taken another step towards that holiest of sci-fi dreams: the 3Dholographic display. Using a spinning mirror covered with a "holographic diffuser," a special DVI implementation, and a high-speed projector, the team's device can project a three-dimensional image that can be viewed from 360 degrees -- regardless of the viewer's height and distance. That's impressive, but that spinning mirror looks pretty dangerous. Check a video of the system in action after the break.
